I dont know how i managed to get 50 at 2/7 arks but i did.
My question is:
Is there a way to track the story? Atm i am in the desert place where theres technology but i did tortoyk (avoid that place if you can) and the arena island (kind of samurai place). Question is why am i not collecting any ark and its getting very very long played like 15+ hours. Am i in the right path?!

Yes you are

Tortoyk cant be avoided.

You can take a break from the main quests after Vern questline.

Damn then im just gonna follow up, im already 50 and i avoided all sidequests

Quests marked in blue are your “main quests” for the continent that you’re on or going to.
